Workers from the King County Road Services Division will begin constructing a new bridge spanning Fifteen Mile Creek on 240th Avenue Southeast, north of Southeast Tiger Mountain Road, beginning today.

During construction, there will be a temporary road to provide access until the new bridge is completed, estimated to be in late October or early November.

The aging bridge is structurally deficient and the foundation is “scour critical,” according to the King County page on the project. Since sustaining flood damage in 2009, it has supported only one lane of traffic.

With the new bridge, drivers will have a wider precast slab structure that ensures construction that is more efficient and more economical than other designs.
